There is no effective control over the pressure and position of riveting during assembly, and the consistency of the products in the actual process is very poor. Such products have the need for nut locking, and manual locking is currently used. The angle after locking cannot be controlled, resulting in the inability to align during assembly, so that the nut cannot be assembled OK. After the existing equipment is assembled, the material is directly unloaded manually, resulting in too many manual actions, which affects the technical problem of production efficiency.
